IMPORTANT SERVICE SAFETY PRECAUTIONS

Service work should be performed only by qualified service technicians who are thoroughly familiar with all of the following safety checks and servicing guidelines:

PLEASE READ BEFORE ATTEMPTING SERVICE

1. Line voltage must be kept within ± 10% of the rated voltage.

2. When operating at line voltage, confirm the DC

voltage at TP1 is 108V ± 0.5 V (Adjust VR601).

3. DO NOT DISCHARGE, ARC, OR MEASURE HIGH

VOLTAGE WHEN HIGHT VOLTAGE LEAD IS

CONNECTED TO CRT. DISCHARGE 2ND ANODE

OF CRT ONLY AFTER HIGH VOLTAGE LEAD

HAS BEEN DISCONNECTED. DO NOT DIS

CHARGE HIGH VOLTAGE LEAD AT ANY TIME,

DAMAGE TO COMPONENTS MAY RESULT.

4. While the monitor is in operation, do not attempt

to connect or disconnect any wires.

5. Disconnect all power before attempting any

repairs.

6. When the power is on, do not attempt to short

any portion of the cricuit. This shorting may cause

damage to the components of the circuits.

WARNING

1. For continued safety, do not attempt to modify

the circuit.

2. Disconnect the AC power before servicing.

3. Semiconductor heat sinks are potential shock

hazards when the chassis is operating.

SERVICING THE HIGH VOLTAGE SYSTEM AND PICTURE TUBE

When servicing the high voltage system, remove

the static charge by connecting a 10kohm resistor

in series with an insulated wire (such as a test

probe) between the chassis and the anode lead.

(The AC line cord should be disconnected from

the AC outlet.)

-2-

1. The picture tube in this display monitor employs

integral implosion protection.

2. Replace with a tube of the same type and number

for continued safety.

3. Do not lift the picture tube by the neck.

4. Handle the picture tube only when wearing shatter

proof goggles and after discharging the high

voltage anode completely.

X-RADIATION AND HIGH VOLTAGE LIMITS

1. Be sure all service personnel are aware of the

procedures and instructions covering X-radiation.

The only potential source of X-ray in a current solidstate display monitor is the tube. However,the

picture tube does not emit measurable X-ray

radiation if the high voltage is as specified in the

"high voltage check" instruction. It is only when

high voltage is excessive that X-radiation is

capable of penetrating the shell of the picture

tube, including the lead in glass material. The

important precaution is to keep the high voltage

below the maximum level specified.

2. It is essential that servicemen have available at

all times an accurate high voltage meter. The

calibration of this meter should be checked pe

riodically.

3. High voltage should always be kept at the rated

value -no higher. Operation at high voltages may

cause a failure of the picture tube or high voltage

circuitry and,also under certain conditions,may

produce radiation in excess of desirable levels.

4. When the high voltage regulator is operating

properly there is no possibility of an X-radiation

problem. Everytime a color chassis is serviced,the bright

ness should be tested while monitoring the high

voltage with a meter to be certain that the high

voltage does not exceed the specified value and

that it is regulating correctly.

5. Do not use a picture tube other than that specified

or make unrecommended circuit modifications to

the high voltage circuitry.

6. When trobleshooting or taking test measurements

on a display monitor with excessively high volt

age, avoid being unnecessarily close to the dis

play monitor. Do not operate the display monitor

longer than is necessary to locate the cause of

excessive voltage.

BEFORE RETURNING THE DISPLAY MONITOR

Fire and Shock Hazard

Before returning the display monitor to the

user,perform the following safety checks:

1. Inspect all lead dress to make certain that the

leads are not pinched or that the leads are not

lodged between the chassis and other metal parts

in the display monitor.

2. Inspect all protective devices such as nonmetallic

control knobs, insulating materials, cabinet backs,

adjustment and compartment covers or

shields, isolation resistor-capacitor net

works, mechanical insulators,etc.

3. To be sure that no shock hazard exists,check for

leakage current in the following manner:

• Plug the AC line cord directly into a 120volt AC

outlet. (Do not use an isolation transformer for

this test)

• Using two clips leads,connect 1.5 kohm, 10 watt

resistor paralleled by a 1.5uF capacitor in series

with all exposed metal cabinet parts and a known

-3-

earth ground such as electrical conduct or

electrical ground connected to earth ground.

• Use a SSVM or VOM with 1000 ohms per-volt or higher sensitivity to measure the AC voltage drop

across the resistor. (See Figure 1.)

• Connect the resistor to all exposed metal parts having a return path to the chassis(metal cabinet,

screw heads, knobs and shafts,escutcheon,etc.)

and measure the AC voltage drop across the

resistor.

• Any reading of 0.3volt RMS (this corresponds to 0.5milliamp.AC) or more is excessive and

indicates a potential shoc~ hazard which must be corrected before returning the display monitor

to the user.

THEORY OF OPERATION

I.POWER SECTION

1. LINE INPUT STAGE The input section converts the AC line voltage into a crudely filtered and unregulated DC voltage

which powers the switching regulator.

1)Filter

To keep noise from being conducted down the

power line a low-pass filter isolates the switcher.

The conducted noise is mostly differential and

can be reduced by 'X' capacitors and a common mode transformer.

2)Power supply

This design utilizes a discontinuous flyback topology operating in current mode. This results in a

multiple output switcher who's outputs track well.

No output filter chokes are needed and slower

diodes can be used. The fast transit response

maintains picture integrity. Cycle by cycle current

limiting makes the switcher short circuit proof.

2. P.W.M IC STAGE

1) p.w.m. integrated circuit

The UC3842 (1C601) is an integrated current mode

pulse width modulator. It consists of an oscil

lator,error amplifier, current-sense comparator,

under-voltage lockout,and an output MOSFET

driver stage.

2)Oscillator

The oscillator consists of a pull up resistor from

the 5V reference to pin 4 and a timing capacitor

to ground. When the voltage on pin 4 lamps up

to 2.8V a flip flop is set. An internal current source

is activated which pulls down,discharging the

-10-

timing capacitor to a 1.0V level. This resets the

current source and starts the next cycle. Oscillator frequency is approximately equal to 1/0.55RC.

The discharge time is a function of the internal

current source and the timing capacitor. The

discharge time should start when the horizontal switch is turned off. It should time out in about

the center of the flyback pulse. The discharge time should equal the storage delay of Q303 plus

one half of the flyback time. Synchronization can be achieved by means of adding timing pulses

to the timing ramp from a reference.

3) Output

The UC3842(I C601 ) has a single totem-pole out

put capable of driving 1.0A peaks and 200mA

average. The peak current is self limiting.

4) Current sense comparator

Current mode controllers inherently keep close watch over the switching transistors current. Pin3

is connected to a voltage comparator which shuts

off the output when current reaches the desired

level,as prescribed by the error amplifier. This way the controller will only let the needed amount

of current be stored on the output transformer.

5)Error amplifier

Voltage on pin2 is compared with an internal 2.5V

2% source. Errors in output voltage are amplified

to pin1 where they are frequency compansated

by an RC back to pin2. This error voltage is

internally dropped by 1.4V ~nd divided by 3 before

being fed to the current comparator.

6)Vcc

The UC3842(I C604} draws very little current in

start up mode. There is enough power. from the

line bleeders R632 and R607 to slowly charge

C618 to the 16 volts need to start the switcher.

When switching begins the Vcc falls quickly but

before it drops to the 10 volt turn off level the

phase lock loop section of the monitor should

be up and running sending power through the

sync transformer to keep the UC3842 alive.

3. Swiching Power Trans Stage

1) Power Transformer

Transistor MTP4N85(Q601) starts off a cycle by

allowing current to flow into the primary of T603.

As current ramps up with time, the voltage across

current sense resistor R621 also ramps to a point

where IC604 determines enough power has been

stored and turn off Q601. As the voltage on Q601

flies upward, power dumped through the main

power transformer and through diodes into the

different supplies. Primary ringing which could

over voltage Q601 is clamped by 0610. To keep

radio frequency radiation to a minimum and

reduce transistor heating, a turn off snubber net

work is placed across Q601. The transformer has

a center leg gap with no gap in the outer legs.

This greatly reduces the flux radiating from the

cores. There also may be a large copper strap

around T603 to short out stray flux.

2) Rectification and Filters

Current from the secondary windings are rectified

and filtered to create the desired Voltages. Low

internal series resistance electrolytic capacitors

keep the ripple voltage low. Small high current

capacitors quickly return charging current to the

source.

II.MAIN SECTION

1.HORIZONTAL STAGE

1)PLL

A phase lock loop is used to synchronize the

horizontal switch to the timing pulses from the

computer. Storage delay in MJH16010A(Q303) is

compensated for by the PLL. Incomming H.sync

is level translated by MPS2222A(Q301) then fed

into the input of the phase comparator. Transistor

PN2907(Q304) watches the falling edge of the

flyback pulse. When the flyback pulse falls to

within a few volts of ground a raising edge is

sent to the other input of the PLL phase com

parator. The phase comparator is used in an edge

lock mode. Integrated circuit MC14046B(IC301)

pin 13 is in a high impedance mode most of the

time. If the raising edges fed into pin 3 and 14

do not coincide, pin 13 goes into a low impedance

stats for the time difference. Depending on which

edge leads the other, current will be fed into or

pulled out of the filter capacitors C308 and C309

2) Horizontal-Drive Transistor VN0606M(Q302) when turned on drives

off the horizontal switch MJH16010A(Q303). At

the same time current is stored on the trans

former T301. When VN0606M(Q302) opens up,

this stored charge kicks up and supplies turn on

current for MJH16010A(Q303). Resistor R302 sets

the average power level to the base drive circuit.

Transformer T301 is surrounded by snubbing cir

cuits.

3)Horizontal-Output

- 11-

On the right hand side of the screen, transistor

MJH16010A(Q303) conducts current through the

deflection yoke to ground. This current comes

from the "S" correction capacitor,C316 and C317,

which have a charge approximately equal to the

supply Voltage. Diode MUR8100(D303) allows cur-

rent, for the left hand side of the screen, to flow

from ground back through the deflection yoke to

C316 and C317.

4)Flyback Capacitor

The flyback capacitor connects the hot side of

the yoke to ground. This component determines

the size and length of the fJyback pulse. If any

adjustment is needed in second anode voltage

this capacitor can be altered. Capacitors C312

and C313 must be prcision high voltage high

current components.

5)"S" Correction

Capasitor C316,C317 are used to correct for

outside versus center linearity in the horizontal

scan. The voltage on C316,C317 have about 33

volts of parabola plus the DC horizontal supply.

If the val ue of C316, C317 are red uced this

parabola will increase, reducing the size of the

outside characters and increasing the size of the

center characters.

6) Horizontal-Linearity

In the yoke current path there is a saturable coil.

Just like a size coil any inductance in series with

the yoke will reduce the size of the picture. This

saturable coil will change inductance depending

on the at the start of trace, the linearity coil has

. an inductance of 20 percents of that of the yoke.

By the center of trace the linearity inductance

has decreased to about 4 percent of the yoke

where it remains for the rest of the trace. This

variable inductor should be adjusted so the right

and left sides of the picture are the same size.

7) HN Regulator Section

The patented hight voltage regulator sits between

the supply and the top of the primary of the

flyback transformer. An onboard switching

regulator is powered from the 12 volt supply. It

watches the second anode voltage through a 300

mega ohm resistor in the flyback transformer.

During flYback the regulator pulls the top of the

fJYback transformer negative some amount at the

same time the flyback pulse is raising the other

end. In this way the size of the pulse as seen by

the fJyback transformer can be varied to keep the

second anode voltage constant under load.

8) Focus Modulation

Each part of a cathode ray tube focuses at a

different voltage. The focus voltage at the center

may be several hundred volts below the top

and bottom with the right and left sides being at

a defferent level. To get the best looking picture

over the entire tube, the focus voltage is modulated with both a vertical and horizontal signal.

The vertical parabola is fed into a high voltage

amplifier 2SC3675(Q401 ). 2SC3675(Q401 ) swings

the focus voltage at the vertical rate. Mixed in

with this signal is another parabola at the horizon

tal rate which comes from L401. The focus ad

justment VR401 sets the do focus voltage and

bias on 2SC3675(Q401).

9) Sub-Brightness

The fJyback pulse is voltage doubled to get 1200

+ volts to run the master brightness poten

tiometer that controls G2.

2. VERTICAL STAGE

The TDA 1670(IC201) incorporates all of the neces

sary functions for providing the yoke of a monitor c'

or television receiver with the current required for

vertical deflection. Incorporated in silicon are a

synchronizqble oscillator, ramp generator, voltage

regulator, vOrtage doubler and power amplifier.

1) Osctllator

-12-

The oscillator is an integrator (pins 4 to 3) and

a two threshold comparator which swiches pin 6

high or low to allow the charging/discharging of

C201. 0201 allows the charge and discharge

ramps to have defferent slopes. Vertical sync

pulses sent in on pin 8.

2) Ramp Generator

The ramp generator is mode up of a current

generator, controlled by current in pin 7, and the

capacitor from pin 9 to ground. The slope,and thus the size of the linear ramp is adjustable by

varying the current pulled from pin 7. This ramp is buffered on pin 10.

3) Power Amplifier

A power amplifier, with input on pin 12, compares

the ramp on pin 10 to the current ramp through

the yoke, R210 and C204 stabilizes the hight gain

power amplifier. Yoke current flows from pin 1,

through the yoke, the DC blocking capacitor, a current sampling resistor, and to ground. Voltage

representing yoke current is then fed back to the input of the amplifier to be compared with the

reference ramp.

4) Voltage Doubler

In order to obtain sufficiently short flyback time,

a voltage greater then that required during scan

ning, must be applied to the yoke. The flyback

generator, during flyback only, applies to the

power amplifier a voltage equal to double the

supply voltage. Pin 15 charges a capacitor up to

the supply vOltage during trace and then sets this

capacitor in top of the power supply during retrace, thus doubling the available Voltage.

5) Vertical Linearity

The ramp from pin 10 is subtracted from the ramp

across R214 and the results are fed back to the

size input of the TDA1670(IC201).

6) Vertical "5"

The TL431 (1C401) and C402 with R215 from an

integrator. The vertical ramp across R214 in

tegrated becomes the vertical parabola on the

output of TL431 (1C401). This parabola is fed back

to the vertical size input of the TDA1670(IC201)

to compensate for "5" distortion. The parabora is also used to drive the vertical focus modulator.

Diode D401 resistors R215,R402,R404 and

capacitor C401 develop a bias voltage.

7) V-Centering A current sources is connected to the cold side

of the vertical yoke. Transistor MPSU01 (Q201) can pull a DC current from the yoke causing the

picture to move up. Potentiometer VR204 should be set to vertically center the data, net the raster,

on the screen.

III. VIDEO SECTION

1.Sync stage

1) Sync processing

To help understand the complex sync processing, please refer to both the schematic and timing

diagrams at the end of this document.

a) Vertical sync

Vertical sync is detected by a low pase filter and

an 'XOR' gate. Pin 8 of CN4A contains vertical

sync.

b) Horizontal sync

Horizontal sync undergoes several stage of

prccessing.

c) Polarity Restoration

-13 -

The polarity restoration circuit, an XOR gate, will

restore sync polarity if it was fed inverted into

the TIL sync input. The RC time constant in the

low pass filter is about 1 second. If the input is

low with short positive pulses a low pass filter

inputs a low to the XOR input B. The output of

the XOR gate will be the same as the input.

Likewise if the input is hight with short low going

pulses the low pass filter will input a high to the B input of the XOR gate causing it to invert the

sync. This way the syncs coming out of the

polarity restoration circuit will always have short

positive pulses except during vertical.

2) H-PHASTE

The second half of the 74LS221 is used for data

centering. The one shot triggers with the reading

edge of sync and time out with the back edge

of the flyback pulse. The data centering poten

tiometer should be set to center the picture within

the raster

3) Video-amplifier

The video amplifier card resides on the neck of

the tube.

4) Pre-amplifier

The MC10H125(IC112) is a quad translator for

interfacing data and control signals between the

MECL section and saturated logic sections of

digital systems. The MC10H125(IC112) incor

porates differential input and schotky TTL ''totem

pole" outputs.

2) Power Video Amplifier

This two transistor cascade amplifier has both

emitter and collector peaking to get the best

frequency respose. The resistor on the base

reduces the chance of oscillation and also helps

to protect the amplifier from tube arcs. The output

of the amplifier is further isolated from tube arcing

by a carbon composition resistor and an arc

arrestor.

3) Regulators

Three voltafges are used to run the video amplifier

and sync processing circuit. The 50 volts is used

by the video power output amplifier. The -8 volts

is reduced to -5 volts by the 7905 regulator for

used by MC10H125.

2. PRE-ASSEMBLY INSPECTION AND HANDLING INSTRUCTIONS

Caution:

Be sure all handing of the CRT display is

done by the CRT mounting brackets. At no

time should the wires be used as a means

of moving or carrying a given CRT display.

The CRT neck is the most fragile part of the

CRT display module and extreme care

should be taken not to bump, tap, or other

wise excess force on this neck.

Before applying power to the CRT display

an inspection should be performed to insure

that any foreign material has not been

dropped in any part of the CRT display.

1. Insure that the proper signal and power con

nections are, made in accordance.

2. Apply power to CRT display under test and

allow CRT display to stabilize for a minimum

of 30 minutes.

Note: All adjustments have at the factory.

This procedure is to insure that these adjustments have been made correctly.

3. When turn external brightness control to max

imum and raster should be slightly visible.

4. Check CRT display for proper centering.

5. Check CRT display for the specified active

charater area per page 5'" 6 of this manual.

6. Check geometric distortion.

7. Check focus.

S. Check power supply voltages in accordance

per page 5 of this manual.

- 21-

3. CAUTION FOR SERVICING

Be sure to provide power supply sequence

of more than 100mS.

power ON-OFF

Do not turn OFF power supply when the

CRT heater is not sufficiently heated. Other

wise, CRT may be burned in spot.

In case of servicing or replacing CRT, high

voltage sometime remains in the anode of

CRT. So, completely discharge high voltage

before servicing or replacing CRT so as to

prevent a shock to the serviceman.

In this case, discharge to the external con

ductive coating(aquadac) of CRT.

Discharging to other places will cause

troubles. The heat sink of horizontal output

transistor is applied with B +. So, do not

earth it in case of servicing. In case of storaging or transporting it, be

sure to take some countermeasures for

static electricity. When using a soldering

iron, be sure to connect it to the earth.

The unused terminal should be soldered

without fail.
